I think you may be under a bit of a misunderstanding if I've read your post correctly.
Is this a CD that he's bought that has elearning on? If that's the case, it will certainly show zero free space because you can't write files to a commercial CD. You can only write them to a writable CD. Similarly, you can't delete files from a commercial CD, or move them to another location on the CD. You can, however, copy them to your laptop's hard drive.
If you double click on the CD drive and it shows you what files and folders are on the CD, then there's nothing wrong with it, I don't think. What happens when you double click on one of the files or folders? Does it open?
Sorry if I've misunderstood the problem.
